xml data handling regex find replace with conditional values -


i got xml file looks this

<documentelement> <table1> <date>2013-08-24</date> <time>00:07:23</time> <type>in</type> <number>393483419761</number> <name>marc</name> <message>lorem ipsum</message> </table1> <table1> <date>2013-08-24</date> <time>00:09:09</time> <type>out</type> <number>1215468498561</number> <name>marc</name> <message>lorem ipsum</message> </table1> <documentelement>

what want check date value , if month 01, add <month>january</month> after </date>, , if month 02 add <month>february</month> , on. got far either:

<date>(\d{4})-01-(\d{2})</date> <date>$1-01-$2</date> <month>january</month>

or i'd like:

<date>(\d{4})-(\d{2})-(\d{2})</date>  if ($2 = 01) { <date>$1-$2-$3</date> <month>january</month> }  elseif ($2 = 02) { <date>$1-$2-$3</date> <month>february</month> }

whats usual way handle , manipulate data this?

normally if parsing xml use real parser instead of regular expressions. in particular case simple operation want do. go on each line, print it, , if current line date, extract month , print additional line.

here's example python script that.

import re months = ["january", "february", "march", "april", "may", "june", "july",           "august", "september", "october", "november", "december"] open(your_xml_file) f:     line in f:         print line         match = re.search(r'<date>\d{4}-(?p<month>\d{2})-\d{2}</date>', line)         if match not none:             print months[int(match.group('month')) - 1]

note, fail insert whitespace or add else attributes date. that's why it's better use real parser. if format stated, faster write small throw away script this.
